[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 - Figure 5As shown, a special explosion-proof heater for paint booths includes a heater body 1; the front end of the heater body 1 is rotatably connected to two sets of protective cover plates 20, and the protective cover plates 20 are provided with a moving mechanism, which includes two sets of connecting rods 21, the connecting rods 21 are rotatably connected to the protective cover plates 20, the top of the connecting rods 21 is rotatably connected to the bottom end of the moving block 23, the moving block 23 is threadedly connected to the rotating rod 24, and the threads on the left and right sides of the rotating rod 24 are rotated in opposite directions. The rotating rod 24 is rotatably connected to the inside of the casing 25, and the casing 25 is fixed to the heater body 1 by welding. The left side of the rotating rod 24 is connected to the output shaft of the heat-resistant motor 26, and the front end of the casing 25 is provided with two sets of through slots 22;

[0024] During operation, in the prior art, multiple groups of explosion-proof heaters are installed inside the paint booth to dry the workpiece or equipment. A cover is provided at the front end of the explosion-proof heater to protect the explosion-proof heater. The cover needs to be opened when the explosion-proof heater is working, and is closed again during the paint spraying operation. However, there are generally a large number of explosion-proof heaters installed inside the paint booth, and it is time-consuming to open and close the covers one by one. The structural design of the moving mechanism realizes the function of facilitating the opening and closing of the protective cover 20. When the protective cover 20 is to be opened or closed, the rotating rod 24 inside the casing 25 is first rotated under the drive of the heat-resistant motor 26. Since the threads on the left and right sides of the rotating rod 24 have opposite rotation directions, the rotating rod 24 rotates. On the contrary, the moving blocks 23 threadedly connected on the left and right sides of the rotating rod 24 move toward or in the opposite direction. When the moving block 23 moves in the opposite direction, the connecting rod 21 will push the protective cover 20, and the protective cover 20 rotates on the heater body 1. At this time, the protective cover 20 will gradually open. Similarly, when the moving block 23 moves toward each other, the protective cover 20 will close. Two groups of through grooves 22 are provided on the front end of the shell 25. The through grooves 22 are used to ensure the normal movement of the moving block 23, and also limit the moving range of the connecting rod 21, so as to avoid the opening and closing angle of the protective cover 20 being too large. The top end of the connecting rod 21 does not contact the through groove 22, and the bottom end does not contact the heater body 1, thereby reducing the friction generated by the connecting rod 21 during the movement.

[0025] Furthermore, multiple groups of baffles 31 are glued and fixed on the through slot 22, and the baffles 31 are made of silicone material;

[0026] During operation, the structural design of multiple groups of blocking bars 31 realizes the function of blocking paint, so as to protect the interior of the shell 25 and prevent more paint from being sprayed into the interior of the shell 25 through the through groove 22 during the painting process.

[0027] Furthermore, the moving block 23 is penetrated by two sets of guide rods 27, and the left and right sides of the guide rods 27 are welded and fixed to the inner wall of the housing 25;

[0028] During operation, the guide rod 27 passes through the moving block 23 to guide the moving block 23 when it moves on the rotating rod 24 , thereby ensuring that the moving block 23 can move stably on the rotating rod 24 .

[0029] Furthermore, two sets of fixing rings 28 are rotatably connected to the rotating rod 24. The fixing rings 28 are provided with arc-shaped notches 29. The top ends of the fixing rings 28 are welded and fixed to the inner wall of the housing 25.

[0030] During operation, the fixing ring 28 is rotatably connected to the rotating rod 24 to provide support for the rotating rod 24 so that the rotating rod 24 can remain stable and not shake when rotating inside the housing 25. An arc-shaped notch 29 is provided on the fixing ring 28 to ensure that the fixing ring 28 will not abut against the guide rod 27.

[0031] Furthermore, a gasket 30 is glued and fixed to one side of the fixing ring 28 close to the moving block 23, and the gasket 30 is made of silicone material;

[0032] During operation, the washer 30 is used to provide a buffer between the fixed ring 28 and the moving block 23 , preventing the moving block 23 from directly contacting the fixed ring 28 , thereby reducing wear on the moving block 23 .

[0033] Furthermore, the outer side of the heat-resistant motor 26 is provided with a protective shell 32, and the protective shell 32 is welded and fixed on the casing 25;

[0034] During operation, the protective shell 32 is used to protect the casing 25 to reduce the amount of paint sprayed on the casing 25 .

[0035] Working principle: In the prior art, multiple groups of explosion-proof heaters are installed inside the paint booth to dry workpieces or equipment. A cover is provided at the front end of the explosion-proof heater to protect the explosion-proof heater. The cover needs to be opened when the explosion-proof heater is working, and the cover needs to be closed again during the paint spraying operation. The number of explosion-proof heaters installed inside the paint booth is generally large, and it is time-consuming to open and close the covers one by one. The special explosion-proof heater for the paint booth in this case realizes the function of facilitating the opening and closing of the protective cover 20 through the structural design of the moving mechanism. When the protective cover 20 is to be opened or closed, the rotating rod 24 inside the casing 25 is first rotated under the drive of the heat-resistant motor 26. Since the left and right sides of the rotating rod 24 are opened The thread rotation directions are opposite, so the moving blocks 23 on the left and right sides of the rotating rod 24 are threadedly connected and move toward or in the opposite direction. When the moving block 23 moves in the opposite direction, the connecting rod 21 will push the protective cover 20, and the protective cover 20 rotates on the heater body 1. At this time, the protective cover 20 will gradually open. Similarly, when the moving block 23 moves toward each other, the protective cover 20 will close. Two groups of through grooves 22 are provided on the front end of the shell 25. The through grooves 22 are used to ensure the normal movement of the moving block 23, and also limit the moving range of the connecting rod 21, so as to avoid the opening and closing angle of the protective cover 20 being too large. The top end of the connecting rod 21 does not contact the through groove 22, and the bottom end does not contact the heater body 1, so as to reduce the friction generated by the connecting rod 21 during the movement.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
